I agree. Maybe brighten up the map or change the color palette or make the contrast sharper. Either way, it's hard to see things. I can't tell how far vision goes on the minimap or when I'm looking at fog, the area it's covering isn't well defined. Back in wc3, when you looked at an area covered in fog you could clearly see the terrain. But in dota2, it just feels like pure black. Can't see where ramps are or camps when looking at it through fog.
